Answer:11.9 inches
Step-by-step explanation:
Circumference(c)=75inches
Pi=3.14
Circumference(c)=2 x π x radius(r)
75=2 x 3.14 x r
75=6.28 x r
Divide both sides by 6.28
75 ➗ 6.28=(6.28 x r) ➗ 6.28
11.9=r
Therefore radius=11.9 inches
The formula for the area of a circle is pi*r^2. 3.14*16^2 = 803.84 centimeters squared
In a circle, the measure of an inscribed angle is half the measure of the intercepted arc ⇒
arc BAD = 2*∠BCD = 2*104 = 208°
arc BCD = 360 - arc BAD = 360 - 208 = 152°
